AUTOMATIC NAUGHT-SIOP FOR ADDING-MACHINES.

To l W/IU/l/ it may Iron urn: V

lie it known that l. vVlLLIAM W. LASKICR, a citizcn oi' the iinited States, residing in Brooklyn. in theeounty of Kings and State of New York, have invented certain new and useful Improven'ients in Automatic Machines, of which the-following is a specification.

This invention relates to card accounting machines in general. and more particularly to automatic naught stops.

The present invention is particularly applicable to a machine such as illustrated in the copending application of James Powers, Serial No. 698,887, filed May 22, 1912.

Among the main objects of the present invention, it is aimed to provide a naught stop that will positively anchor. the typecarrying sectors innaught printing position when setting pins have not been extended into their path of movement.

These and other features, capabilities and advantages of the present invention will appear from the suhjoincd detail description of one specil ic embodiment thereof, illustrated in the accompanying drawings, in

Figure l is a side elevation, partly in section. showing the naught stops in sectoranchoring position.

Fig. 2 is a tragincntal rear elevation of the same.

Fig. 3 is a tragmental view similar to that Shown in Fi 1 Fig. 4 is a tragmcntal view similar to Fig. 3, showing a type-carrying sector released. from the naught stop.

Fig. 5 is a fragmental view similar Fig. 55, showingthe position of the stop. when being retracted.

Fig. 6 is a detail perspective of one of the shutters.

Fig. 2' is a detail setting pins.

- Fig. 8 is a fragmental detail showing the position of a shutterrelative to a naught stop when the naught stop is in anchored posltion. 4

Fig. 9 is a tragniental detail showing the position oi a shutter relative to a'naug'ht stop when the naught stop is released from its type-carrying sector. '4

' In the ei'nbodiinent shown in Fig. 1, there to naught perspective of one of the setting pins of the shutter-box 21 which extend from are provided the type segments 11 pivotally mounted on the shaft 12, on which shaft is specifictis lion of Letters Patent. Patented July 15, 1919. l Application filed February 38, 1916. Serial No: 79,014,

also pivotally mounted the cheek plates 13 of the retracting rod 14 andthe type carrying sectors 15, the tvpe segments 11 and type-carrying sectors 15 being-resilient ly connected to the cheek plates 13 by the springs 16, end the sectors 15 and segments 11 connected to one another by the slot and pinconncction 17. For operating the retracting rod'M, the link'18,'p1votally connecting the cheek plates 13 with the crank sector 19, is secured to the actuating' shaft 20. There is also provided a shutter-b0$r '21 provided with the shutters 22,- which have inclined upper edges that are resiliently maintained in the path of movement of the by the springs 25 (Fig. 2). The shutters 21, in the present instance, as distinguished from those illustrated in the. co-pending application of James Powers, Serial No. 802,363,

filer Nov. 22. .1913, have, instead of the upwardly extending naught stop, an upwardly extending rear plate portion 26 wliiclnwhen its shutter is anchored in the path of movement of the pins 24, will serve as-the active supporting portioitof the naught stop formring the present ii nprovenient.

The naught stop forming the present 1m )roveinent com Rises, essentiall ins 27 on I a the segi'uents 11 to be engaged by the upwardly extending hook arms 28 of the le .vers 29 pivotallyconnected to the rod 30 at their rearwardly extending portions 31, such rearwarrlly extending portions being spaced from one another by the fingers 32 of the spacing bar 33 which is secured to the lower side of the transversely extending block '34 fastened to the rear end of the main frame A, themed 30 being supported gers 32. The levers 29 are also provided with downwardly extending arms 35 which areadaptedto rest on the plate portions 26 i i of the shutters 22 when the naug t stops are disposed. in segment-anchoring position.-

For further spheing thele'vers 29 from one another and guiding tion, there are provided the spacing rods 36 the upwardly extending plate portion 37 secured to the "front end of the shutter-box 21 to the downwardly extending plateportion 38 secured to the main by such finthem in their opera-.

frame A, such rods being of comparatively smallv diameter and extending between the se ments 11 and the levers 29.

From the foregoing it will be seen that, when the segments 11 have been retracted by the retracting rod 14, and the ievers are positioned on the plate portions the hook arms 28 will engage the pins and anchor such segments 11 in naught position, and. that, whenever a pin 24% is set thereby rocking a shutter 22, it will remoyethe support for a lever 29 thereby permitting such leverv to descend and therewith withdraw its hook arm 28 out of engagement with the pin 27; Thereupon the segments 1]. are free to move forwardly and be stopped by the pins 24. J

For retracting the levers 29, seawaretractingrod 39 is provided, which is secured to the freearms of the levers 40 pivotally connected to the downwardly extending portions of; the bearing brackets 41 secured to the block 34. Pivotally connected to the u wardly extending ortions of the bearing rackets 41 arethe evers 42 which extend; forwardly, and at their free ends support the cheek plate-engaging rod 43.

For moving the rods 43 and 39 in. parallelism, the levers 42 and 40 are ivotally connected to one another by the inks t4, spell linked-at, in the present instance, being bent to circumvent the block 34. For resiliently maintaining the rod v43 in its downward position against the cheek plates 13, the springs 45 are provided, connecting the levers 4:2 with the block 34. F or limiting the downward movement of the levers 42, there is provided alimiti'n'g rod 46 which is socured to the frame A;

The operation of the retracting arrangement is substantially as followsrwwhen printing has taken place, and the segments 11 are to be rot'url'icd, the cheek plates 13 are retracted by the link 18. As such cheek plates 13' approach their rearward move i1ient,'tliey'will engage the rod 43 and thereby root: the lovers -11! and 40 and the leverrctracting rod fii), until the lever-retracting rod 39 engages and raises the level-s25) above the plate portions 26, whereupon the pins 24, having previously been released, the

shutters 22 will immediately be returned to normalv lever-supporting position, and the lower arms 31 of the lovers 29 Will thereiipon engage the upper suri'aces of the plate por tions 26, while their hook armsfZS will engage the pins 27. i

It is obvious that various changes and modifications may be made in the details of construction without departing from the general spirit or scope of this invention.
